CUSPIDOR.

Specification of Letters Patent.

Patented May 7, 1907.

Application filed February 41.1907. Serial No. 355,609.

To al?, whom, t may concern.-

Be it known that we, HARRY VVILsoN and ROBERT L. GREENWELL, citizens of the United States of America, residing at fashington, in the District of Columbia, United States of America, have invented certain new and useful Improvements in Cuspidors, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in cuspidors, and has for its primary obj ect the provision of novel means for flushing the cuspidor at any desired time, whereby the same may be kept in a cleanly and sanitary condition.

Another object of the invention is to pro vide acuspidor with a lloat so constructed as to be supported on liquid contained within the cuspidor bowl, and to be depressed into such liquid, and, when so depressed, to act as a plunger or like element to displace the liquid contained in the cuspidor bowl, so that the same is forced upwardly around the Yfloat and projected over the mouth or funnel of the latter to 'l'lush the same.

Still further objects of the invention reside in the novel construction of the cuspidor bowl, receptacle or casing, and in the novel construction of float co-acting with said bowl, receptacle or casing, whereby the object of the invention is accomplished.

In the dr-awings accompanying this application, there is shown a practical embodiment of the invention as the same has been practiced, and in describingl the invention in detail, reference will be had to said drawings, and the construction therein shown will be described in detail, but it is to be understood that we do not desire to limit ourselves to the precise construction shown, since it will be obvious that various changes may be made in the details of construction, without departing from the spirit of the invention, or the scope of the same as defined in the claims.

In the drawings Figure 1 is a perspective view of a cuspidor constructed in accordance with my invention. Fig. 2 is a central vertical sectional view of the same, the bonnet carried by the float being shown in side elevation. Fig. 3 is a detail view partly broken away, showing a modification in which a rod is connected to the bonnet instead of the foot-button shown in Figs. l and 2.

To put our invention into practice, we provide a casing l, generally termed in the art a receptacle or bowl. This bowl may be constructed of any desired material, and may be of any desired size and shape. Generally the same has been made in an annular form, though such form is not essential to the eiect of working of the device. The said bowl is provided, intermediate its top and bottom, vwith an inwardly extending combined guide and deiiector 2, acting as a guide for the lioat, and also as a deilector or means for causing the vliquid as it rises around the float to be projected over to the mouth of the latter. At its upper edge or rim, the said bowl l is rovided with a top delector 3, the said de lector being also rfor the purpose of projecting the rising luid over onto the lioat contained within the bowl. The dellector 3 is generally formed by inclining thc material at the rim or top of the bowl l, and the guide or deilector 2 can be advantageously formed by routing the material so as to force the same inwardly, as clearly shown in the present illustration.

In use the bowl l is adapted to have a quantity of liquid placed therein, as illustrated in Fig. 2 of the drawings, such liquid preferably containing a disinfectant. Supported within the bowl 1, upon said liquid, is a float comprising the base 4l, side walls 5, and funnel mouth 6, the central opening 7 of said Iioat being covered by a bonnet 8 suitably supported as by feet or standards 9, said bonnet being provided on its apex with a foot button l0, or may, if desired, and as shown in Fig. 3, have a rod ll connected thereto whereby the float may be depressed by hand, without requiring the operator to stoop during the operation.

Where the float is constructed of thin metal, the space between the funnel mouth 6 and the base 4 is made air-tight, so as to form an air chamber, whereby the lioat will more readily tend to remain approximately on top of the liquid, the weight of the float not being sulicient to depress the same into the liquid to any greater extent than is shown in Fig. 2 of the drawings.

In operation, whenit is desired to flush or clean the mouth 6 of the float, which mouth 6 it will be observed acts as the funnel of the cuspidor, the said float is depressed, either by placing the foot on foot button 10 IOO and pressing downwardly on the float, or by depressing the latter by the rod 11. The forcing of the float down into the liquid 12 displaces the latter, and while a quantity of this liquid rises through the opening 7, a very consderable quantity thereof is caused to rise around the sides of the float, and is checked in this upward movement by the inwardly extending deiiector 2, and as the upper edge of the float passes below the deflector 2, the liquid is caused by said deflector to be projected over onto the funnel mouth 6, whereby to flush the same. As soon as pressure on the float is relieved, the latter rises, and all liquid in the funnel mouth 6 drains down into the bowl, carrying with it any matter which may have accumulated on the upper face of the funnel mouth 6.

The iioat is of a diameter slightly less than the smallest diameter of the deflector 2, whereby the said deiiector acts, to a certain extent, as a guidefor the float in its vertical movement. The iioat, however, being of less diameter than the smallest diameter of said deflector, will not become lodged` underneath said deiiector when the upperv end of the ioat is depressed below the said deflector 2, as the deilector being rounded, and the upper edge or rim of the float also being preferably slightly rounded as shown at 14, the liquid pressing against the float will cause the same to work out from underneath the deflector 2 and rise to its normal position practically on top of the liquid after pressure is relieved. The deflector 3 at the top or rim of the bowl is provided for catching any of the liquid which may not have been deflected or projected inwardly by the deflector 2, and preventing the liquid from splashing out of the bowl.

Where usedy in factories, shops and the like, the cuspidor is generally provided with the foot button, so that the same may be operated by foot pressure, but where it is desired to use the device in hospitals, dentists offices, or the like, the bonnet is preferably provided with the rod 11 whereby the float may be depressed at will and the cuspidor mouth or funnel kept iiushed and in a sanitary condition.

Having fully described our invention, what we claim as new and desire to secure by Letters Patent is:

1. In a cuspidor, a bowl adapted to contain liquid, a ilange formed on the inner face of said bowl intermediate the top and bottom thereof and constituting a combined iioat guide and a water deflector, a hollow float supported solely by the liquid in said bowl or receptacle having a funnel shaped top terminating in a central opening, a bonnet supported above said opening, the said float being of less thickness than the distance between the flange and the bottom of the bowl or receptacle whereby the float may be depressed below said flange and the liquid as it rises around the lioat be projected by aid ilange 'on to the funnel shaped top of the oat.

2. In a cuspidor, a bowl or receptacle adapted to contain liquid, a flange carried by said bowl or receptacle intermediate the top and bottom thereof and constituting a float guide, a float freely movable in the bowl having a funnel-shaped mouth terminating in a central opening, a bonnet supported by the float and disposed above the central opening thereof, and an inwardly projecting water deflector adapted when the float is depressed Y in the liquid in said bowl, and the liquid rises around the float, to project said liquid over on to the funnel-shaped mouth of the float and iiush the same.

- In testimony whereof we affix our signatures in the presence of two witnesses:
